Allen paid back the compliment, interviewing Kenneth the following year - (on "Writing For The Stage" - on the occasion of a 3-week run of his play, "The Red Robins", at New York's St. Clemens Theater). It (that interview) is included in Koch's collection The Art of Poetry. It's also, happily, available on line here.

Of course, there's also Allen's wonderful hommage poem, "Homework" - "If I were doing my Laundry I'd wash my dirty Iran/ I'd throw in my United States and pour on the Ivory soap/ scrub up Africa, put all the birds and elephants back in/ the jungle...."

There's also the Columbia (academic, or rather counter-academic) connection. Interesting to think that Kenneth's landmark poem, "Fresh Air" was published the very same year as "Howl".

Kenneth Koch lecturing at Naropa (he was, of course, the consummate teacher), can be accessed here and here, a 1981 reading at Naropa is available here.

Interviews with him can be read here (1989) and here (1993), and here (1996 - on the occasion of him being awarded the Rebekah Johnson Bobbitt National Prize for Poetry, supervised by the Library of Congress (the previous year, he'd won the highly prestigious Bollingen award)).
